    摘要： A partial-seepage drainage pipe includes a wall surface of circular profile which is corrugated over the majority of the pipe circumference. Adjoining the circular wall surface is a base having a bottom surface and side wall segments. The pipe has a mating sleeve molded on in one piece at one end, which is adapted to receive the free end of a corrugated pipe segment and has slit-like water seepage openings in the corrugated wall surface.In order to attain a tight mating-sleeve connection, the bottom surface of the base and the corresponding bottom surface of the mating sleeve are embodied such that they arch in a slightly convex fashion.

    摘要： A pipe connecting element serves to connect pipes, which consist essentially of a continuous inner pipe and connected with it, extending radially outwards, projections, which serve to stiffen the pipe. To make such a pipe connecting element suitable to the light construction concept of double walled pipes or corrugated pipes on the one hand and achieve high load capacity in the direction of the pipe axis and good hydraulic properties on the other, the pipe connecting element consists of connected with each other sections, which are constructed by a core pipe and a jacket pipe. Adjacent sections are connected on their butt joint surfaces in such a manner that the core pipes and the jacket pipes each of these adjacent sections are connected with each other. Additionally, the core pipe and the jacket pipe of each section are firmly connected with each other.

    摘要： An apparatus for the production of plastic pipes with transverse grooves comprising half shells each having a mold recess which are arranged on a machine bed driven in a cycle. The half shells are assembled in pairs in a molding path to form a complete mold, the injection head of an extruder being arranged at the beginning of the molding path. Furthermore, the half shells are provided with vacuum channels, each vacuum channel being connected to a respective mold recess. The vacuum channels are joined into vacuum connections formed in the machine bed, and the half shells are provided with cooling channels which join into cooling water inlets and outlets in the machine bed. In order to ensure an exact setting of the half shells during the molding operation, the cooling channels, on the one hand, and the vacuum channels on the other hand, in a given half shell are completely separated from each other.

    摘要： An apparatus for the manufacture of corrugated pipes of thermoplastic plastics, which has circulating mold segment halves disposed in two opposite rows subsequent to an injection head, includes a wedge element for separating the mold segment halves. This wedge element is displaceable parallel to the direction of production. Further, grab equipments are provided to be displaceable,counter to the direction of production, by which one additional mold segment half at a time can be moved to the downstream end of a molding path, removed from the latter in the direction of production and moved into a parking position.

    摘要： An apparatus for the manufacture of transversely contoured tubing from thermoplastic material. The tube emerges in the plastic state from an extrusion nozzle and is guided into a mold composed of a plurality of mold sections in series, with inner side working surfaces forming the transverse contours. Each of the mold sections is composed of two mold halves which are arrayed along a straight molding run in two confronting rows and which are circulated. In the circulation, the first two mold halves are moved apart and out of the molding run at the end of the molding run and are guided to a return run on which they are separately returned to the beginning of the molding run where they are rejoined to the preceding mold half. The mold halves are guided on the return run in a continuous, accelerated and then decelerated movement by a transfer mechanism which couples and uncouples from the mold halves as actuated by pneumatic cylinders under the control of limit switches.
